ATBNT COMBINED GRAIN ANDOIL CAR.

SPECIFICATION forming part of Letters Patent No. 313,932, dated March 17, 1885.

(N0 model.)

To all whom it may concern.-

Be it known that I, J OHN B. Garrrnrenr, a citizen of the United States, residing at J effersonville, in the county of Clarke and State of Indiana, have invented certain new and useful Improvements in a Combined Grain and Oil Oar; andl do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to railway-cars for transporting freight.

It is a wcll-known fact that cars which go east loaded with grain from the great grain regions are frequently returned emptyat great expense, and that cars suited for carrying oil have to be returned empty to the oil regions from all directions, because oil-cars are unsuited for carrying anything else.

The object of this invention is to adapt a car to be loaded to its full limit of weight with oil, to carry the same to its destination, and then to be loaded with grain or other freight to its full capacity of weight on its return-trip.

To this end my invention consists in the construction and combination of parts forn1- ing a freight-car, hereinafter described and claimed, reference being had to accompany ing drawing, which is aside elevation ofa car,

, part in section, illustrating my invention.

A represents car-trucks of any usual construction, upon which the body B is mounted. This body consists of an iron tank of any form suitable for a car'body and suitable to carry oil.

0 represents a wooden box or car-body built on top of the iron tank or car B.

The box-car C is provided with a wooden bottom D, raised enough above the top of the tank B to permit free circulation of air'between and to preservetheinterior of the boxcar entirely free from any oil which may leak or slop out of the tank. 1 haveshown the oiltank as partially separated into two compartments by the slanting form of the upper side thereof, yet united in the middle. This union may take place within the contour of the tank, as shown, or the tank may be separated into two distinct compartments and connected by a pipe or pipes beneath.

The form of tank here shown gives two advantages to the car: first, by its top terminating in an angle the oilis less likely to assume a dangerous'vibratory or wave motion from the sudden stoppage and starting of the car; secondly, the interior bottom of the upper box or canbody, following the slant of the tank, is

well suited to the quick delivery at its een- 6o tral door, G, of grain carried in bulk, the same sliding freely down the floor from the ends toward the center of the ear.

E represents a pipe by which the oil-tank may be filled, and F a dischargepipe therefor.

The tank may have any suitable provision for top vents to free it from gas in hot weather or from the effectof shaking. The tank might be built with a horizontal top, ora top of any other shape suited to receive a box-car on it,

but I prefer the top shown for the reason stated.

By means of my invention the tank may hold enough oil to be a full car-load to carry one Way, and the box or car-body above it may hold grain enough for a full load on the re'turirt-rip, and will deliver it readily at its door, thus effecting a great economy.

Having thus fully described my invention,

what I claim, and desire to secure by Letters ing of a box, 0, fitted on top of the tank, and

having a bottom, D, separated from the top of the tank by an air-space, and slanted on its bottom from its ends toward its middle, substantially as shown and described.

2. The combination of an oil-tank, B, prac- 9c tically separated into two compartments by its top slanting from the ends toward the middle, and a box or car-body fitted on the top thereof and having its bottom slanted from the ends toward the middle thereof, substantially as 5 shown and described, for the purpose specified. In testimony whereof I affix my signature'in presence of two witnesses.

JOHN R. GATHRIGHT.
